Work: Calculate the value of equation -(400/500)*log(2,400/500)-(0/500)*log(2,0/500)-(100/500)*log(2,100/500) .
Question type: Mathematical calculation
Solution:
-(400/500)*log(2,400/500)-(0/500)*log(2,0/500)-(100/500)*log(2,100/500)
=-0.8*log(2,400/500)-(0/500)*log(2,0/500)-(100/500)*log(2,100/500)
=-0.8*(-0.321928)-(0/500)*log(2,0/500)-(100/500)*log(2,100/500)
=-0.8*(-0.321928)-0*log(2,0/500)-(100/500)*log(2,100/500)
=-0.8*(-0.321928)-0*0.693147-(100/500)*log(2,100/500)
=-0.8*(-0.321928)-0*0.693147-0.2*log(2,100/500)
=-0.8*(-0.321928)-0*0.693147-0.2*(-2.321928)
=0.257542-0*0.693147-0.2*(-2.321928)
=0.257542-0-0.2*(-2.321928)
=0.257542-0-(-0.464386)
=0.257542-(-0.464386)
=0.721928
Answer:-(400/500)*log(2,400/500)-(0/500)*log(2,0/500)-(100/500)*log(2,100/500)=0.721928
